Influence of Different Control Parameters on the Flux Density and Loss of Stator Core in the Switched Reluctance Motor

Abstract

Switched reluctance motor has the advantages of the high efficiency, low cost, strong fault tolerance, and high reliability. A 5.5 kW, 12/8 pole switched reluctance motor is designed. The novel transient electromagnetic field-control circuit coupled calculation method of switched reluctance motor is proposed. The influence of different PWM switching angles, chopping current thresholds, and hysteresis current widths on flux density and loss of stator core in the switched reluctance motor is studied in detailed by this novel method. Controller harmonics are considered during this calculation. The change of the flux density and loss of stator core in the switched reluctance motor is compared and analyzed under the different controller parameters. The reliability of the calculation method and accuracy of the calculation results are verified by experimental values.
